Security checks for vulnerabilities and agentic risk

Overview

This skill is a simple Anthropic brand-style guide with broad activation wording but no code, credentials, persistence, or hidden actions.

Installers should understand that this skill may be invoked broadly for Anthropic-themed visual styling; use it when you actually want Anthropic branding applied, and review generated artifacts for brand appropriateness and trademark considerations.

A.I.G

Vulnerability Patterns

Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
Agent Memory PoisoningWrites attacker-controlled rules into memory that affect later sessions
Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally
Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs

Vague Triggers

Medium

Category: Not specified by scanner
Confidence: 94% confidence
Finding: The description says the skill applies to 'any sort of artifact that may benefit' from brand styling, which is overly broad activation language. In an agent setting, this can cause the skill to be invoked in contexts where it is unnecessary or inappropriate, increasing the chance of unintended post-processing of sensitive or unrelated outputs.
